Taw qhia
Polyvinyl chloride (PVC) cov kav dej tau dhau los ua qhov muaj nyob hauv kev tsim kho niaj hnub thiab cov kav dej, vim lawv cov kav ntev, pheej yig, thiab ntau yam. Cov txheej txheem tsim khoom ntawm cov kav dej PVC muaj cov txheej txheem sib txawv uas hloov cov ntaub ntawv raw rau hauv cov kav dej uas peb tso siab rau ntau yam kev siv.
Cov khoom siv raw: Lub hauv paus ntawm PVC yeeb nkab ntau lawm
Txoj kev taug kev ntawm PVC yeeb nkab raug pib nrog kev yuav khoom ntawm cov khoom siv raw. Cov khoom tseem ceeb yog polyvinyl chloride resin, cov hmoov dawb tau los ntawm ethylene thiab chlorine. Additives, xws li stabilizers, plasticizers, thiab lubricants, kuj tau koom ua ke los txhim kho cov khoom ntawm cov khoom kawg.
Kauj Ruam 1: Mixing thiab Compounding
Cov khoom siv raw yog ua raws li kev sib xyaw ua ke thiab kev sib xyaw ua ke. PVC resin, additives, thiab pigments yog ua tib zoo sib xyaw ua ke nyob rau hauv meej proportions siv high-speed mixers. Qhov no homogeneous sib tov yog ces extruded rau hauv ib tug uniform blend.
Kauj Ruam 2: Extrusion: Shaping cov yeeb nkab
Cov sib xyaw PVC sib xyaw yog pub rau hauv lub tshuab extruder, lub tshuab ua kom sov thiab quab yuam cov khoom los ntawm kev tuag zoo li qub. Cov tuag txiav txim siab qhov profile thiab txoj kab uas hla ntawm cov yeeb nkab raug tsim. Raws li cov molten PVC sib tov dhau los ntawm kev tuag, nws yuav siv sij hawm ntawm qhov xav tau thiab tshwm sim raws li cov yeeb nkab txuas ntxiv.
Kauj Ruam 3: Txias thiab Calibration
Cov yeeb nkab PVC extruded tseem kub thiab malleable thaum nws tawm hauv qhov tuag. Txhawm rau kom khov thiab teeb tsa cov yeeb nkab qhov ntev, nws dhau los ntawm chav da dej txias lossis txau chav. Txoj kev ua kom txias sai sai no ua kom cov yeeb nkab khaws nws cov duab thiab kev ua haujlwm zoo.
Kauj Ruam 4: Txiav thiab ua tiav
Cov yeeb nkab PVC txias yog txiav rau hauv qhov ntev ntev uas siv cov saws tshwj xeeb. Qhov kawg ntawm cov kav dej yog trimmed thiab beveled los tsim cov npoo du, huv si. Ntxiv cov txheej txheem tiav, xws li luam ntawv lossis kos npe, tuaj yeem siv raws li qhov xav tau.
Kauj Ruam 5: Kev Tswj Xyuas Zoo
Thoob plaws hauv cov txheej txheem tsim khoom, cov kav dej PVC tau raug kuaj xyuas kom zoo. Dimensional raug, phab ntsa thickness, siab tsis kam, thiab tag nrho cov kev ncaj ncees yog meticulously kuaj xyuas kom ua raws li kev lag luam cov qauv thiab cov neeg siv specifications.
Cov khoom kawg: Ntau yam PVC kav
Thaum cov kev tswj xyuas zoo dhau lawm, cov kav dej PVC tau ntim thiab npaj rau kev faib tawm. Cov kav dej no pom cov ntawv thov hauv ntau qhov kev lag luam, suav nrog kev tsim kho, kav dej, dej, thiab hluav taws xob. Lawv durability, tsis kam mus corrosion thiab tshuaj, thiab yooj yim ntawm installation ua rau lawv ib tug nrov xaiv rau ntau yam dej num.
Xaus
Cov txheej txheem tsim khoom ntawm cov kav dej PVC yog qhov ua pov thawj rau cov txheej txheem tsim khoom niaj hnub thiab kev siv ntau yam ntawm PVC ua cov khoom siv. Los ntawm kev ua tib zoo xaiv cov khoom siv raw mus rau qhov kev tswj xyuas nruj, txhua kauj ruam kom ntseeg tau tias cov khoom kawg ua tau raws li qhov xav tau ntawm ntau daim ntawv thov. Raws li cov kav dej PVC txuas ntxiv ua lub luag haujlwm tseem ceeb hauv peb cov kev tsim kho vaj tse thiab lub neej txhua hnub, kev nkag siab txog cov txheej txheem tsim khoom tom qab lawv muab kev nkag siab zoo rau lawv qhov zoo thiab kev ua tau zoo.
